A microfinishing machine and tooling particularly adapted for lobed cam surfaces such as internal combustion engine camshafts or outer irregular surfaces. The microfinishing tooling includes shoes having a pair of rollers which press abrasive coated film material against the workpiece being machined. The rollers are carried by a plate which is also free to rotate slightly. The roller elements are free to rotate and therefore wear on the tooling is minimized in response to minute motion of the microfinishing film during the microfinishing process. Furthermore, the roller elements closely follow the contours of the workpiece surface to provide a more uniform machining effect. Various configurations for the roller elements are disclosed, including a unitary roller made of a hard material and another embodiment in which the roller is coated with an elastomeric material.
A microfinishing tool for a microfinishing machine in which said tool presses an abrasive coated film against a workpiece cam lobe which is rotated with respect to said tool such that said film machines the cam lobe surface of said workpiece, comprising:
A microfinishing machine having tooling for pressing an abrasive coated film against a camshaft lobe surface as the camshaft is rotated with respect to the tooling causing the lobe surface to be machined, comprising:
